While insertion always perform, random reads are very slow on WiredTiger when the cache can't contains the index. This is consistent during random search or upsert.

Hi dupuisla, we're happy to follow up and engage either via https://groups.google.com/forum/#!search/wiredtiger-users or https://github.com/wiredtiger/wiredtiger/issues.

I'm going to close this for now, because as dan@10gen.com mentioned, this isn't the right forum for native WiredTiger issues. Please get in touch via one of the other channels to follow up.

Hi Laurent,
This issue tracker is meant for issues with MongoDB, including when using MongoDB with the WiredTiger storage engine. The issue you've posted is about using WiredTiger directly. In the very near future, we'll move the issue tracking for WiredTiger to the MongoDB Jira deployment, but for now, we have kept the direct WiredTiger issues tracked via github, here: https://github.com/wiredtiger/wiredtiger/issues.

I've copied michael.cahill from the WiredTiger team, who can help route your issue appropriately. Thanks
Dan
